Gleason was rebuilt as a closer in 2011, though he had only moderate success in that role. After 14 strong innings to start the season in the Mexican League he returned to the Orioles' organization, but he was hit hard in both Double-A and Triple-A. Gleason could bounce between those same levels in 2013. Baltimore has few question marks in its bullpen, so Gleason appears to be blocked at the MLB level.
